Abstract
A subminiature fuse is disclosed comprising two terminals, a substrate, a fusible conductor, and a unitary housing. The unitary housing is sealed and provides increased mechanical strength, thus reducing the risk of a catastrophic failure of the fuse. The upper portion of the fuse terminals are shaped into finger like projections adaptable to mechanically fastening the fusible conductor and the substrate thereto thus facilitating the manufacturing process. In one embodiment the fusible conductor and adjacent portions of the terminals and substrate are coated with a ceramic coating or adhesive. The housing is sealed by ultrasonic welding or preferably in an insert molded plastic enclosure which is substantially devoid of air.
